RFC: provide 3.0.x and 3.1 libc headers

Hi all,

Here's a RFC patch for updating the toolchain linux-libc headers to 3.x variants.

The reason I'm calling it a RFC is:

- I wrote some anonymous python code (and I'm no python coder) to deal with 2.6 / 3.0 tgz location differences. This could have also been done with a variable set in the recipes and used by the .inc. I wasn't sure of the preferred approach, hence the RFC. I'll take no offense corrections here.

- I changed the .inc, but didn't bump the PR of the existing recipes and didn't remove the existing 2.6 variants. If either of these should have been done, let me know and I'll respin.

- I bumped the default to be 3.1. If that's too agressive for the default, and we'd prefer 3.0.8, let me know and I'll respin.

I built and booted all the qemu machines with the 3.1 kernel headers. So from the testing I was able to do, this looks to be safe and ready to go.

This is based on my yocto repo, I also did the changes in my oe-core repository, but I don't have a oe-core contrib branch that I could push to, so I chose to send the yocto variant. If someone points me to who I email for an oe-core contrib branch, I can push that variant as well.

Cheers,

Bruce
